Fuck, I always thought this was a myth, but I guess not... from my extensive three minute Google search, turns out it's 100% real

I'm really curious to see how they affixed the spark plugs to the lugs. I'm guessing glue of some sort.
I'd bet the car originally had lug bolts in a m12x1.25.... which is also a common spark plug thread size
Some hubs use lug bolts into a threaded hub instead of lug nuts on protruding studs. Lug bolts don't seem to be as common as studs.
Not to mention how they're delivering the high voltage to the plugs and how a tiny spark will melt snow. Glow plugs might stand a slightly better chance. Slightly.
Someone hasn't seen one of those compilations of tires flying off the car and killing unsuspecting pedestrians/drivers.
